CARBURETER.

Specification ofv Letters Patent.

Patented Oct. 26, 1909.

Application led October 31, 1908. Serial No. 460,553.

To all whom tt may concern:

Be it known that I, MORTIMER FREDERICK MIVILLE, a subject of the King ofGreat Britain, of Summersdale, Chichester, in the county of Sussex,England, engineer, have invented a new and useful Improvement inCarbureters, of which the followingl isa specification. e

My invention relates to apparatus for the production of carbureted airand more particularly to that class of apparatus provided with a seriesof perforated tubes, some, or all i of which perforations are arrangedbelow the surface of the volatile liquid.

The present invention has for its object certain improvements inapparatus ofthe type referred to by which the air is more thoroughlyimpregnated with carbureted air to the required extent, the wholeapparatus being simple, cheap and effective.

The accompanying drawing is an illustration of one convenient form ofcarbureter constructed in accordance with the present improvements,Figure 1 being a longitudinal section thereof, and Fig. 2 a transversesection of the same.

I construct the improved carbureter as shown preferably of copper andrectangular in form, this vessel being divided longitudinally into upperand lower compartments 1 and 2 respectively by a perforated gauzepartition 3. Immediately beneath this partition 3 I arrange on each sidea circular, square, or other compartment or passage extending for thefull length of the lower or carbureting chamber 2. These compartments orpassages, 4, 5, are each provided at one end thereof with an air inlet6, Fig. 1, from the blower-not shown-under the control of an adjustablevalve or valves for re lating the air supply.

rom one of the air compartments or passages 4 above described a seriesof vertical pipes 7 are arranged at short intervals apart which conductthe air to the bottom of the carbureter 2, and the pipes 7 are thenturned at right angles across the width of the carbureting chamber 2,their lower horizontal parts 8, 8, being perforated as shown. Theperforated pipes 8, 8, are laid in corresponding gutters orcorrugationsl 9, 9, formed in the bottom of the carbureter 2 and are allhorizontally level-as illustrated in Fig. 2 so that they are justcovered with spirit-indicated by the dot and dash lines 10-when theapparatus is in use, the air leaving the Y perforations coming intodirect contact with and passing through saidspirit 10 and at the sametime agitating the latter, a rich gas being thus formed. The aircompartment 5 on the opposite side of the carbureting chamber isfurnished with a number of vertical pipes 11, 11, similar to thosealready described but of less length and their lower ends 12, 12, arebent outward in a downwardly sloping direction so as to lie over thesurface'of the spirit as shown; or, an equal number of tubes 7, 11, maybe employed and arranged so that the lower series of horizontal pipes 8,8, are below the upper series 12, 12, as will be readily understoodwithout further illustration. These pipes 12, 12, are formed withperforations in their lower part by which air is blown downward towardthe yrst'series of tubes, 8, 8, and being practically free fromhydrocarbon dilutes the carbureted air rising from said lower tubes 8,8. The gas thus formed in the carbureter 2 passes through the gauzeartitions 3 to the upper chamber 1 and rom thence is conducted to theservice pipe or gasometer by a pipe 13, in the usual way.

It is important that the upper series of tubes 12, 12, should slope downas described to bring the supply of air nearer the surface of thespirit. Where more gas is consumed more air becomes necessary, and thegreater the volume of air the quicker the spirit 10 is evaporated andconsequently the lower the temperature.

The bottom 14 of the carbureter 2 described is curved or inclineddownward to its center as shown to a central well 15 for the purpose ofcollecting any foreign substances, such as water, dust, or otherimpurities, which can be drawn ofi by a cock 16, and the necessity foremptying the carbureter for cleaning purposes is thus obviated.

17 is a cross corrugation connecting the lower central part of thecorrugations 9, 9, thus completing the perfect draining system to thecentral well 15 above described.

A pet cock 18 is also arranged from the carbureter 2 slightly above thelower series of tubes 8, 8, for the purpose of ascertaining the heightof the petrol 10.

The details of construction of the apparatus may be varied to suitdifferent circumstances.

Apparatus for the production of carbureted air constructed according tomy invention is extremely effective in operation,

cheap in construction, and not likely to get longitudinally divided intoupper and lower. l compartments perforated partition, air-inlet passagesarby a` horizontally disposed ranged below said partition at oppositesides of the carbureter and a series of vertically depending pipessituated at short intervals apart below the air inlet passages, thelower ends of the pipes on one side being perforated and horizont-allyturned to lie along the bottom of the carbureter, while the lower .endsof those on the opposite side are perorated and outwardly bent in adownwardly sloping direction, all substantially as set forth.

2. In a carbureter, the combination of a chamber provided with aplurality of air inlets and an outlet and adapted to contain a free bodyof liquid to be carbureted, and a series of pipes connected with eachinlet, one series having portions lying adjacent the bottom of thecasing and submerged below the level of the liquid and provided withperforations ldischarging upwardly therethrough, the other series ofpipes having portions lying above the level of the liquid and above saidsubmerged porticnsand provided with perforations discharging downwardly.toward the; liquid and toward the upwardly discharging vapor from saidsubmerged portions. A p j y y 3. In a carbureter, the combination of achamber adapted to contain the liquid to be carbureted and provided onits bottom wall with a plurality of grooves, said chamber havingairrpassages, a series of tubes connectedvwith one of sad'passages andlying insaid grooves and discharging airy into the liquid below thelevel thereof, and a series of tubes connected with another air passageand discharging air toward and above .the level of the liquid. Y

In witness whereof I` have hereunto set my hand in the presence oftwowitnesses.
